This article tackles a long‑standing bottleneck by introducing a compilation stack that adapts quantum circuits to the quirks of any fault‑tolerant hardware platform, delivering concrete estimates of qubit count, runtime and classical overhead in one go. By adding the transversal active volume (t‑AV) approach for architectures with long‑range logical links, it shows how even early‑stage fault‑tolerant chemistry simulations could run on as few as 10⁴ physical qubits across photonic, superconducting or neutral‑atom systems. The framework gives researchers and engineers a practical tool to compare disparate technologies and to plan realistic experiments before the next generation of error‑corrected machines arrives.

Summary
The compilation of an algorithm can vary significantly with the choice of physical hardware platform and error correction model. Yet, current compilation frameworks typically commit to a single architecture-hardware configuration, making it difficult to assess resource estimates across platforms. We present a platform-aware compilation framework that re-compiles a quantum circuit into a hardware-compatible instruction set as well as fault-tolerant operations and provides end-to-end resource estimates in terms of physical-qubit count, time-to-solution, and classical processing time. We benchmark the framework by obtaining end-to-end resource estimates for different compilers, each tailored to the functionalities of specific hardware modalities: connectivity, clock speed, and noise model. As part of this framework, we introduce a transversal active volume (t-AV) compilation architecture designed for the efficient execution of fault-tolerant operations in platforms supporting long-range logical connectivity. We benchmark the framework for Hamiltonian simulation of the 2D Fermi Hubbard model as well as for eigenenergy estimation of a small molecule (trimethylenemethane) as a candidate for early fault-tolerant demonstration of quantum chemistry. For the latter, we show that end-to-end quantum simulations can be achieved with $\sim10^4$ physical qubits and runtimes ranging from $10^2$ ms (photonics, superconducting) to $10^5$ ms (neutral atoms).
